For some unknown reason my pod XT live keeps clipping when i bypass the amp and also when i use some of the clean amps :S but when i have distortion on it never clips ???????? WHAT THE HELL IS WRONG WITH IT !!!!!!!

What type of pickups are you using? Have you tried a different guitar to see if this changes the situation? I have run into clean sounds clipping when using active pickups - the solution is to slightly lower the volume on the instrument and the clipping goes away.
